Chemical Equation

A chemical reaction is a process where a chemical substance may decompose into two or more substances; two or more substance may combine to yield new substance(s).

A chemical equation describes a chemical reaction using chemical symbols and formulae.

• The chemical formula on the left hand side shows the starting substances (also called as reactants).
• The chemical formula on the right hand side shows the final substances (called products).
• The reactants and products are separated by the arrow symbol (). The arrow sign stands for “yields” or “react to form”.
